enhance get orchestration request

Enhance get orchestration request to include workflow step
Began working on adding call for activity name
Added call to return activity information
Updated to return last task executed
Added last task executed info to returned string
Updated mocks to fix failing unit tests
Added responses for mocks to Camunda for process and activity history
Added tests to cover taskName changes
Began adding tests to cover changes to RequestHandlerUtils
Added more unit tests for activity lookup
Updated error messages for taskName
Moved properties to application.yaml file
Added unit tests to add more coverage to task retrieval
Moved Camunda calls to CamundaRequestHandler class
Removed unused imports from RequestHandlerUtils
Fixed formatting of tests and removed handler where not used
Removed CamundaRequestHandler from JerseyConfiguration
Added retryTemplate for camunda calls
